Absolutely Nothing Lyrics

I'm on the doorstep with my key turned in the door,
Walk the livin room and you're side on my floor[ Lyrics from: http://www.cloverlyrics.com/e95831-lily_allen~absolutely_nothing_lyrics.html ]
My heart is achin and i've never felt this bad
I pinch myself to check that all of this is real
Keep thinkin i'm not lettin on I feel this sad
Then you've got the cheek to ask me how I feel
